This is not at all a question. We can not read your mind. You have to post the code you have implemented and describe issues with that code.

You can validate this in client side like this

if i click on that checkbox i want that corrsponding ID that' why am saving that id in hidden field. if you did't select any check box the checkedIDs length will be zero

$('[id^="MainContent_rptrFollowup_chkSelect_"]').live("click", CheckCheckBox);

       var checkedIDs = "";
       function CheckCheckBox() {
           var tempid = $(this)[0].id.split('_')[parseInt($(this)[0].id.split('_').length) - 1];
           if ($(this).is(":checked")) {
               if (checkedIDs.search($("#MainContent_rptrFollowup_hdnchkPatientAppointmentID_" + tempid).val()) < 0) {
                   checkedIDs += $("#MainContent_rptrFollowup_hdnchkPatientAppointmentID_" + tempid).val() + ":";
               }
           }
           else {
               if (checkedIDs.search($("#MainContent_rptrFollowup_hdnchkPatientAppointmentID_" + tempid).val()) >= 0) {
                   checkedIDs = checkedIDs.replace($("#MainContent_rptrFollowup_hdnchkPatientAppointmentID_" + tempid).val() + ":", '');
               }
           }
       }

       function chekCkeckBox() {
           var isChecked = false;
           if (checkedIDs.length > 0) {
               $('#MainContent_hdnChkSendMail').val(checkedIDs);
               isChecked = true;
           }
           if (isChecked)
               return true;
           else {
               AlertDialog('You are required to select at least one item from the list to send email.', "eMeditime - Send Mail");
               return false;
           }
           return true;
       }
